Abstract (en)

[origin: DE19613215C1] The invention concerns a centrifugal drum (1) of which the inlet chamber (12) is connected to a discharge chamber (10) via ducts (21), the delivered fluid having to flow radially through rib-free annular chambers (24, 25, 26) on the way to the discharge chamber (10). A through-flow resistance is thereby generated which ensures that the inlet chamber (12) is filled completely. Since the ducts (21) start in the vicinity of the inlet pipe (8), the acceleration of the delivered fluid to the speed of rotation of the centrifugal drum (1) occurs over a small diameter with the result that the stress on the centrifuged material is relatively low.
